The IFAK Add-ons are my personal recommendation to supplement your GB2 IFAK. Some items you need to have readily available to maximize the effectiveness and efficiency of your med gear. Having these items on standby allow you to preserve the factory seal of your IFAK for things you need right away, like trauma shears and your primary tourniquet. The tourniquet sealed in the IFAK is meant to be your secondary backup tourniquet. For shock treatment and hypothermia management, having an Emergency Survival Wrap handy for quick heat retention and/or shelter is critical and shouldn’t require you to break into your sealed IFAK.
